Charles Blunt (1803–1878) – The Apparent Retrograde Motion of the Planets – Hand-Coloured Aquatint Engraving (1842)
This detailed astronomical diagram titled "The Apparent Retrograde Motion of the Planets" (No. 55) was published in The Beauty of the Heavens by Charles Blunt in London in 1842. It illustrates the observed reversal in direction of planetary movement as seen from Earth—a phenomenon caused by differences in orbital speed and perspective. The plate shows concentric planetary orbits, a central sun, and lettered planetary positions that visually explain how the retrograde illusion occurs relative to the zodiac. The coloured bands and geometric layout communicate both scientific precision and visual clarity, characteristic of Blunt’s effort to bring astronomy to a general audience.Charles Blunt (1803–1878) was a British educator and scientific writer best known for his contributions to popular astronomy. His work sought to make complex astronomical concepts accessible to general audiences through both text and engaging illustrations. The work was published by Whitehead ; Co. in London in 1842.Artist or Maker: Charles BluntDimensions: 25 cm x 20 cmMedium: Hand-Coloured Aquatint EngravingDate: 1842Condition Report:This work is in good condition overall.
